Title:
WIRELESS COMMUNICATION SYSTEM, SERVING GATEWAY, NETWORK, AND LOGICAL PATH ESTABLISHING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/183405
Kind Code:
A1
Abstract:
A wireless communication system is provided with: a packet gateway; a plurality of serving gateways; a switching station for controlling the establishment of a logical path; a wireless base station; and a user apparatus. A first serving gateway transmits connection information to another node. When a first logical path is established via the first serving gateway, the packet gateway requests a second serving gateway to establish a second logical path via the second serving gateway. On the basis of the above request, the second logical path is established between the packet gateway and the user apparatus via the second serving gateway.
